SHEET-@TAL CAG 'FOB ROLLER BEARINGS application mea :une 39.1926. seal 1ra-1195i?.

(This invention relates to sheet ntal ca les for roller bearings and is particularly use l in that, type of bearing wherein' the 'roller 5 there are two'rows of such rollers so arran ed on the inner race that the axes of the rol ers of each row areL disposed on a' cone. Many.

- of the features'are adaptedtoother shaped v rollers having theirjouter ends smaller than their inner ends. `One of the objects 'of the`invention being to provide separate' and independently rotatable cages which are capable of mutual support and guidance one vupon the other. 'f

In the drawings accompanying this specication my invention is illustrated applied to a roller bearing ofthe self-aligning type,

in which drawin -Figure lis ,an end elevation of a roller part being show n in central cross section.

Fig. 2 is a central lon 4itudinal section of vthe bearing illustrated in igure 1, and

- ig. 3 is a perspective view of the'cage yin Figures 1 and 2 Iremoved from the bearing with rollers.

The type of bearing upon which this in# vention is especially -useful'is'j the two` row 3io self-aligning 'roller' bearin shown as having an outer ring, 5,p'rovi ed with an inner spherical surface, 6, constituting the trackv for )two rows of rollers,-7, these rollers being Aforlned with 'a curvature `in an axial direcv tion havin suitable radial relation to the radius of t e sphere, 6. The bearing is also illustrated as having an inner-ring, 9, formed with a pair of race grooves, 10, adapted to receive and guide the rollersv in`their move- VThe cage -for each structure, the I'netal having a b'end- 11, continuous with both sides,'12 and 13, of theJ box. At the smaller or outer end of -thebox there are formed through the bend and the 'outeredge'jof the, side "plates a series of notches, v14,' constituting roller sockets or pockets of less depth than 'the length of the fjtontendedroller. The 'metal at the sides of' eacli noteh in both lates slillustrated in the nature of extrudedp liaps'which are` straight 1s curved in an axial direction, and in which',

rings but partlyequipped row of rollers is shownV comprising a conicalftruncated box like in a 'longitudinal direction. eIt will be seen `that the flaps, 15, from the outer/ plate, 12, i

roject outwardly and that the iiaps, 16,

project inwardly.l

rom the inner plate, 13,

-The smaller orouter end of the, box as above explained; is formed bythe bend, '11. The inner end of the box is formed by an" an@` nular lia-nge, 17,. bent 4from one side plate, preferably the outer nplate, 12, toward the other plate. wi In some'instances the rollers will be :assembled in the bearing and in position in the cage byg being snapped in, which operation in some lnstauces will be facilitated by'means outer lands of the inner ring.

. Having 'described my invention I claimand' desire to secure by Letters Patent: x

` -1. A cage, for therollersfof a, two row "F of suitable filling notches, 18, Yformed i through the The pair `of cages are shown as riding upon the rollers and the inner .bex ends or roller bearing `wherein the rollers are smaller at theirouter end and those of each row have their axes disposed on a cone, the cage being formed 'of sheet metal and comprising; a pair of conical truncated box, like structures or the rows of rollers, the metal havin a bend continuous with both sides of each x i at the smaller end, there being a series of pockets formed through the bend and side lates at" this end 'of a depth lesswthan the ength of the intended roller, extruded f iaps projecting from the side plates -at the` sides an annular flange bent vfrom one side plate toward the other forming the other end of -Ofv each notclr for engaging the roller, and v the bo'x,. sch flanges being so formed as to l l be-normally in contact when assembledfin a 0. that each cage' supports and bearingl guides the other.

2.A cage, for the rollers of a' two row roller bearing wherein the rollers are smaller at their outei` ends 'andthose of each rowl have their axes disposedv on-a cone, the cage being formed of sheet metal and comprising; e 'l a pair of conical truncated boxlike structures for the rows of rollers, the metal having-a bend continuous with both sides of each box at the smaller end, there being a series of pockets formed through. the bend and' side pdltes at-'this end-,0in` depth less than the lengt naps, substantially straig p diection, projec ing from thenside plates at notch for engaging the 5 the sides of each h of the intended roller,

extruded ht in longitudn roller and an annular `flange bent from one side plate toward the o ther forming the other 'no1/elses such flanges being so formed end of the b ox in contact when assembled as to be normally guides theother. Signed at New of June, L1926. p
